GoLunco ALTO.—An extensive tree, 40 to 50 ft. high ; wood good ; 
branches patent; leaves very large, ovate or obovate, coriaceous, 
glossy ; stipules the largest seen by Welwitsch amongst Angolan 
Rubiacez ; bracts spathulate, pilose ; calyx shortly tubular, scarious, 
truncate, with an entire margin; capsule 10-ribbed, more or less 
pentagonal, scarcely bursting at the base. At the banks of the river 
Casaballa in Sobato de Bumba ; fl.-bud and young fr. 22 Oct. 1855. 
Native name ‘“ Mungo.” No. 3027. Bumba ; heads of fl.-buds 22 Oct. 
1855. “Mungo,” Cot. Carp. 632, 
Aéranthus Guyonianus Reichenb. f. (Welw. Herb, No. 653), grew as 
an epiphyte on the branches of this tree. This, one of the trees 
called ‘‘ Mungo,” is much prized by the inhabitants of Golungo Alto 
on account of the excellence of its wood, which is used for house- 
building and furniture (see Welw., J.c.). The smaller leaves bear a 
tolerably close resemblance to the foliage of Morelia senegalensis 
A. Rich., a plant of tropical Africa north of the Equator.
